The blades of a helicopter's propeller are perpendicular and congruent. the distance between consecutive blade tips is 24 feet. find the length (b) of each blade.

Answers

47 - 90 = 43

43 - 180 = x

x = 137

Set up the problem using the given picture.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

\frac{2}{5}=\frac{x-18}{x}

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

\frac{2}{5}=\frac{30-18}{30}

\frac{2}{5}=\frac{12}{30}

Check the picture below.

now, recall, both blades are congruent, thus a = b, so c² = a² + b² -> c² = b² + b².
